Use case - When a Due Date is selected, only a future date should be allowed in EDIT Screen.
Note - I knew this can be achievable by adding a validator in workflow Transitions however, I don't want to do that way, the reason being said, I've 40 workflow transitons and for every transitions I've to add to achieve this working (see attached I did that). it will add a lot of load ..
Appreciate your suggestions if this can be achievable by adding a code or via script runner in EDIT Screen
